Ok, il give you the easiest way to make money (using an exploit yes, but no console commands or anything like that) this works on all systems, but I play on Xbox and this is the easiest way ive found to make quick cash, all of these are good ways to do it, and yes, a dragon bone war hammer can be upgraded an sold for close to 10k, but what merchants have that cash??? An the time it takes to level your smithing is mind numbing bc they patched the "iron dagger" exploit on Xbox lol
So here it is, you need 3 things, to have the ritual stone active, get to hags end, the most important, lots of patience lol in about half the time it would take to level your skills to make the money, you can have what you need...look up deep wood redoubts location (if undiscovered) that's where hags end is,once inside hags end, there's a door to the left, walk in, fight the hag til she teleports, then go up the stairs to the throne room, fight her there til teleport, now here's where the trick is, behind the throne is where the dark brotherhood assassin is you loot the ancient shrouded armor from, he's located behind a secret door you have to complete a specific quest INCLUDING all the bonus objectives to unlock it...well, that's normally how you do it lol
Stand next to the door and use the ritual stones power, then go back to the door you entered hags end through and walk back outside...when you "load" on the other side, it will also load all of the minions you rezd w the stone, including the assassin fully clad in the armor...*(notation there's more to this part il explain later) * ...kill him and take the armor, then wait 24hours, use the power and walk back through the door, when you load on the other side, he respawns with another set of the armor on, here's why, the game engine is set to clear dead bodies out after so many days, and respawn them alive (most of them) later (about 30 days)...but in the assassins case the game knows he's supposed to be dead already and "skips" him in the clean up process, he's treated more like a "inanimate object" like a potatoe or chair than a npc...but you can do this until you get bored w it, the cowl will sell for 400g chest for 200g gloves for 60g and boots for about 120g...so about 800-850 total, but the whole armor set weighs 7lbs...so if your like me, I dump everything I have on something else or on my follower when I do this then load up until I can't carry anymore sets of the armor...(which is usually about 40 sets of it) then you just fast travel back to white run and sell what you can, wait 2 days, repeat...then if that's not enough money, I back and do more, he will still be there, (although maybe reloaded behind the wall) bc he's a static in game "item" not a npc to be cleared out...
Since in white run there is the alchemy shop, usually 5-700g, belethor 700g, farengar 500g Adrienne 1100g and ulberth (inside war maidens)1100g you can usually make around 4k every 2 days...with speech leveled to 100 (using the meadery exploit in Riften) w appropriate perks, you can get about 1.5x more than that, so close to 10k every 2 days...
